45
The large joint space between C1 and C2 is called the:
atlantoaxial (zygapophyseal)
What are the three distinctive features of all cervical vertebrae that make them different from any other vertebra?
transverse foramina
bifid spinous process tips
overlapping vertebral bodies
Which position of the thoracic spine best demonstrates the intervertebral foramina?
lateral
Which position or projection of the cervical spine best demonstrates the zygapophyseal joints (between C3 and C7)
AP axial
Which specific joint spaces are visualized with an LAO projection of the thoracic spine?
downside left zygapophyseal joint
Which two thins can be done to minimize the effects of scatter radiation on lateral projections of the thoracic and lumbar spine?
Which position or projection best demonstrates the zygapophyseal joints between C1 and C2?
anterior or posterior oblique of thoracic spine
How much and in which direction should the CR be angled for each projection?
AP axial projection of the C spine
an anterior oblique of the C spine
a posterior oblique of the C spine
15-20° cephalad
15-20° caudad
15-20° cephalad
Which projections of the cervical spine demonstrates the left intervertebral foramen?
RPO and LAO
In addition to using a long SID, list the two positioning techniques you can use to lower the shoulders to visualize C7-T1 for a lateral projection of the C spine.
weights that are 5-10 lbs.
expose on full expiration
List the two positions or projections that will project the dens in the center of the foramen magnum
AP open-mouth
Fuchs method (AP)
A lateral cervical spine radiograph demonstrates the zygapophyseal joint spaces are not superimposed. Which type of positioning error(s) may lead to this radiograph outcome?
rotation of spine
A radiograph of a lateral thoracic spine projection shows the intervertebral foramina and intervertebral joint spaces are not clearly demonstrated. Which type of problems can lead to this radiographic outcome?
CR should be perpendicular to long axis of T spine and spine should be parallel to IR
A pt who was involved in an MVA 3 days earlier is experiencing severe neck pain and comes to the radiology department for a cervical spine series. The pt is not wearing a cervical collar. Should the tech take a horizontal beam lateral projection and have it cleared before proceeding with the study? Explain.
yes, the radiologist must clear pt for further exam
A pt with a possible Jefferson fracture enters the ER. Which specific radiographic position best demonstrates this type of fracture?
AP open-mouth C spine
A radiograph of an AP open mouth projection of the cervical spine demonstrates the upper incisors superimposed over the top of the dens. What specific positioning error is present on this radiograph?
excessive flexion (chin is down)
A pt comes the the radiology department for a follow-up study for a clay shoveler’s fracture. Which spine projections will best demonstrate this type of fracture?
AP and lateral C-spine
A pt comes to the radiology dpt. for a follow-up study 6 months after having spinal fusion surgery of the lower cervical spine (C5-C6). The surgeon wants to check for AP mobility of the fused spine. Beyond the basic cervical spine projections, what additional projections can be taken to asses the mobility of the spine?
hypertension and hyperflexion lateral
Which of the following technical factors is most important in producing a high-quality CR image?
Decrease SID whenever possible
Minimize the use of grids
Decrease kVp as much as possible
Collimate as closely as possible
collimate as closely as possible
